I'm about to purchase my first 2011. A Bul Armory sas ll tac in 9mm. This is the also the first time I have spent that much money on any gun. I want to customize a few things on the gun, Change the magwel color, thumb safety color and a few more things. I dont trust myself to complete these tasks competently, and so I am looking for a gunsmith in my area to take the job. I'm in the Howell area, any suggestions? Someone that you have used and was satisfied with their work. Thanks.
